ABSTRACT:
A process for the production of stainless steel in a top blown oxygen converter wherein the rate of carbon removal during the refining process is improved particularly from the standpoint of minimizing oxidation of other alloying elements such as chromium. This is achieved by introducing oxygen mixed with an inert gas through a tuyere and into the metal being refined either simultaneously during a portion of the oxygen blowing or after the completion of oxygen blowing but in any case it is continued until the required carbon level has been achieved, while the interior of the converter above the liquid level is maintained at subatmospheric pressure.
